Namuhla sizokhuluma ngohlobo lwenkalankala eyaziwa ngokuthi enkulu kunazo zonke emhlabeni. Imayelana ne- inkalankala kakhukhunathi. Igama layo lesayensi ngu I-birgus ballast. Yize sithathwa njengenkalankala enkulu kunazo zonke emhlabeni, lesi sitatimende sinama-nuances athile. I-nuance ebaluleke kakhulu ukuthi yiyona enkulu kunazo zonke emhlabeni ngoba inkulu kune-crab enkulu yaseJapan nenkalankala eyaziwayo yesicabucabu. Umehluko kowedlule ukuthi uhlala unomphela emhlabeni.
Kule ndatshana sizocubungula izici, indlela yokuphila, ukondla nokukhiqiza kabusha inkalankala kakhukhunathi.
Izici eziyinhloko
Le nkalankala ingeyomndeni we-arthropod futhi ihlobene kakhulu ne- inkalankala njengoba kuchaziwe ngezansi. Izilinganiso zakhe zokufuna ukwazi zidale ukuthi ososayensi abaningi bamchaze njengesilo sangempela. Isici sokuqala esigqame kakhulu ngosayizi omkhulu kakhulu. Iyakwazi ukukala amakhilogremu ama-4 futhi ibe nobude obucishe bube yimitha elilodwa. Lokhu kumenza abe inkalankala enkulu kunazo zonke neyesabekayo emhlabeni.
Ngalobu bukhulu obukhulu le nkalankala idinga izindunduma ezinkulu zemilenze yangaphambili nezinzipho ezesabekayo ezisebenza ukucindezela isisulu sayo. Lezi zinzipho zinamandla okuchoboza noma afana nalawo ezinye izidalwa eziningi ezizingela ngokuluma.
Yize ngike ngacubungula uhlobo lwenkalankala yomhlaba, ukuqala kokuqala empilweni yalesi silwane kwenzeka olwandle njengoba kwenzeka kwezinye izinkalankala. Izihlahla zikakhukhunathi ziyizibungu ezincane nje ezingena phakathi kwemisinga yolwandle phakathi nenyanga yazo yokuqala yokuphila. Njengoba zikhula, zivele isikhashana zisuka phansi kolwandle zizofuna uhlobo lwegobolondo elingazenza ikhaya lazo elihambahambayo. Yingakho ngike ngasho phambilini ukuthi kubukeka kufana nenkalankala.
Lo mbulali wezinsalela oqhamuka ekudaleni indawo yakhe yokuhlala futhi aguquke ukusuka endaweni yokuhlala emanzini aye endaweni yasemhlabeni kungenxa yesitho esiyingqayizivele esibizwa ngokuthi yi-branchial lung esithuthuke ekuziphendukeleni kwemvelo futhi siphakathi nendawo kwamaphaphu namaphaphu. Njengoba inkalankala kakhukhunathi ikhula emhlabathini, isuka kwenye iponcha iye kwenye njengoba kwenza inkalankala.
Ukudla kwenkalankala kakhukhunathi
Ukudla kwama-invertebrate asengozini yokuqothulwa akuwona nje ukhukhunathi njengoba umuntu angaqagela. Kuyiqiniso ukuthi ukhukhunathi uyingxenye eyinhloko yokudla kwezinkalankala, yingakho igama lazo elijwayelekile. Ukuze kufinyelelwe kusayizi omkhulu kangaka, inkalankala kakhukhunathi kumele idle cishe yonke into. Izidingo zabo zokudla zifinyelela eqophelweni lokuthi bakwazi ukuphendukela kwesidumbu ukuze banelise izidingo zabo.
Zikhula kancane kakhulu futhi azifinyeleli ekuvuthweni kokuzala kuze kube yilapho sezineminyaka eyisithupha ubudala. Kodwa-ke, Lokhu kunjalo ngoba isikhathi sokuphila kwalesi silwane singafinyelela eminyakeni engama-30 nengama-40.
Ukudla kusekelwe ikakhulukazi kunoma yiluphi uhlobo lwezinto eziphilayo ezitholakala emgwaqeni. Izithelo ezibolayo, amaqabunga, amaqanda kofudu, ngisho nezidumbu zezinye izilwane. Lolu hlobo lokondla lwenza kungabi nzima kakhulu ukukhula futhi yingakho lufinyelela kusayizi omkhulu kangaka. Ososayensi bakwazile ukubhala ukuthi kwezinye iziqhingi lapho ukudla kwabo okuyinhloko, ukhukhunathi, lokhu kungaba izinkalankala zikakhukhunathi, baba uhlobo lwenkalankala. Lokhu kungenxa yokuthi iyakwazi ukuhlasela noma yisiphi esinye isilwane esifinyelele kuso.
Ukwenza lokhu, isebenzisa izinzipho zayo ezinkulu nemilenze yangaphambili ukuhlasela izilwane ezinjengezinkukhu, amakati, amagundane noma esinye isilwane esingafinyelela kuzipho zaso. Njengoba sazi, ukuvula ukhukhunathi akuyona into elula. Kodwa-ke, lezi zilwane azinankinga yokuvula lesi sithelo esiqinile. Lapho bethola ukhukhunathi badinga kuphela ukusebenzisa impintshisi yangaphambili ukuyidabula futhi basuse yonke ingubo enemicu.
Ukuthola ukudla, le nkalankala iwusizo lomuzwa omuhle kakhulu wephunga nezimpondo zalo ezinamandla ezisebenza ukuthola ukudla noma ngabe kutholakala amabanga amade. Imvamisa zidla ebusuku zihlale usuku lonke zicashe emigedeni emincane yamatshe noma zivame ukuzimbela imingxuma yazo ukuze zizivikele kwezinye izilwane ezidla ezinye. Izidalwa ezithinta kakhulu abantu bakakhokho kakhukhunathi ngabantu.
Inkalankala kakhukhunathi esengozini
Abantu balezi zilwane abakaze bafundwe ngokuphelele. Ngenxa yalokhu noma cha kuyaziwa ngokuphelele ukuthi mangaki amakhophi akhona esewonke. I-International Union for Conservation of Nature (IUCN) ikubeke njengedatha engeyinhle. Ucwaningo lwakamuva luveza ukuthi inani lalezi zinkalankala zehle kakhulu. Lokhu kwehla kwabantu kungenxa yezici ezahlukahlukene ezinjengalezo esingazithola ukusetshenziswa ngokweqile kanye nokuntuleka kwemithetho kohulumeni ukuvikela lezi zinsizakusebenza.
Njengoba inani labantu landa futhi nezilwane ezifuywayo zifakwe eziqhingini eziningi, kube nezinguquko ekuziphatheni, ukondla kanye namaphethini okudlela esikhathini sokudla. Ngaphezu kwalokho, lokhu kwanda kwenani labantu kukhiqize ukusetshenziswa okukhulu kwenkalankala kakhukhunathi ngenxa yenyama yayo emnandi. Le nyama ihlonishwa kakhulu phakathi kwabakhileyo eziqhingini futhi banokubaluleka okukhulu kwezenhlalo namasiko.
Isidingo senkalankala sande kakhulu ngakho abantu bancipha kakhulu. Kunocwaningo lwango-1989 olwaveza ukuthi eziqhingini lapho kutholakala khona le nkalankala, isilinganiso sezinkalankala ezingama-24 zazizingelwa ngenyanga. Njengoba ungacabanga, ngezinhlobo zalolu hlobo amakhophi angama-24 ngenyanga kuyinombolo eyeqile. Lokhu kungalingana nokuzingelwa kwaminyaka yonke kwezinkalankala ezingama-49.824 ezisatshalaliswa phakathi kokusetshenziswa kwasendaweni kanye nokuthunyelwa kwamanye amazwe. kwezinye izindawo zomhlaba, ikakhulukazi eNew Zealand.
Banuka ukwazi okuningi mayelana nenkalankala kakhukhunathi kanye nomongo wayo ekubeni sengozini yokuqothulwa.
